按键值对PHP中的JSON对象进行排序

当

$data

Array(    [0] => stdClass Object        ( [name] => Morts par Déshydratation [score] => 4 [id] => dwater        )    [1] => stdClass Object        ( [name] => Réparations de chantiers [score] => 87 [id] => brep        )    [.] => ....)

您可以

usort()

<?php usort($data, function($a, $b) { //Sort the array using a user defined function    return $a->score > $b->score ? -1 : 1; //Compare the scores});print_r($data);   ?>

输出：

Array(    [0] => stdClass Object        ( [name] => Décoration [score] => 112 [id] => deco        )    [1] => stdClass Object        ( [name] => Réparations de chantiers [score] => 87 [id] => brep        )    [2] => stdClass Object        ( [name] => Campeur téméraire [score] => 77 [id] => camp        )    [3] => stdClass Object        ( [name] => Drogues [score] => 49 [id] => drug        )    [4] => stdClass Object        ( [name] => Ouverture de porte [score] => 11 [id] => door        )    [5] => stdClass Object        ( [name] => Morts par Déshydratation [score] => 4 [id] => dwater        ))
